Site plans for Narrogin, Western Australia: drawn in minutes
Need a site plan for a shed, patio, carport, deck, pool or granny flat in Narrogin? Site plans and assessments in minutes, drawn over the real lot.
Building in Narrogin
On a Narrogin lot, open space is the limit people forget: each density code sets a minimum, and every roofed structure counts against it. Most siting numbers come from the state's housing codes, but the shire can set its own figures for outbuilding sizes, site works, street setbacks, boundary walls and garage and carport setbacks through a local planning policy. Before drawing anything, look at the state's heritage, native vegetation, landslide and bushfire mapping, which applies across Narrogin.
Keep a shed within the state's standard outbuilding figures and off any heritage place, and development approval is usually not required; go bigger and the shire assesses it. For applications lodged near you, the shire office is the place to ask. Pools of any real depth need a permit and a barrier, with the barrier inspected on a regular cycle. Where a sewer runs through the lot, Water Corporation keeps a clear access way round its maintenance structures and headroom under any roof, and expects to sign off work near its pipes before it starts.
What we hold for Narrogin
For Narrogin we hold the council’s own rules for:
- sheds, garden sheds, garages and carports
- patios, pergolas, louvred roofs, decks and shade sails
- pools, fences and retaining walls
- granny flats
- driveways, water tanks and shipping containers
At each lot we check the state’s mapping for flood, bushfire, landslide, heritage and native vegetation.

How approval works in Western Australia
In Western Australia the local government is the permit authority and issues the building permit, and an application can arrive with the design already checked by a private registered building surveyor, who issues a certificate of design compliance. Some small structures need no building permit, but every structure still has to meet the planning side: on a house lot, the Residential Design Codes and the local planning policies. Work that meets their deemed-to-comply standards, on a place that is not heritage protected, needs no planning approval; work that does not goes to the local government as a development application, judged against the design principles. The site plan shows the structure's distance to each boundary, its wall height and the open space left on the lot. The lot's density coding decides how close a structure can go, as per the Residential Design Codes (R-Codes) and the Building Act 2011.
Drawing the plan
Type the property address, the lot’s real boundaries load from official land records in Western Australia, and you place the structure over the aerial view. The plan prints to scale with boundary lengths, setback distances, a north arrow, a legend, a site coverage table and a title block, as the site plan for a building permit or a development application.
What a certifier in Narrogin will ask you
How high can a retaining wall and a fence go?
Each takes its own height test, and a retaining wall carrying a fence has its own approval. Both heights go on the sheet for the certifier to read together.
How big can a granny flat be, and how far from the house?
The council caps a granny flat’s floor area, and some councils also limit how far from the house it may stand. The sheet prints the floor area and dimensions the distance to the house.
Is the lot in an overlay, and what is the zoning?
A flood, bushfire, heritage or character overlay can bring a planning approval on top of the building approval, and the zone decides which of the council’s rules apply. The mapped overlays are read at the lot as the structure goes on the plan.
How deep is the pool?
The depth decides whether the water needs a barrier, and the barrier has to be in place before the pool is filled. The barrier is what gets inspected, so the sheet shows where it runs and every gate with its swing.
The figures for your own lot are read in a minute, from its address.
Every question a certifier asks is on the Western Australia page.
